Improvement in roofing-tile presses



JOHN KOEHLER, OF WARREN, OHIO.

Letters Patent No. 110,859, dated January 10, 1871;` antedated January 6, 137.1.

IMPRCV'EMENT IN ROOFlNG-TILE PRESSES.

The Schedule referred to in these Letters Patent and making part of the seme.

I, JOHN KOEHLER, of Warren, in the county of Trumbull. and State of Ohio, have invented certain Improvements in Roofing-tile Presses, of which the following is a speciticaton.

The lirst part of my inventionl relates to the pressroller, said roller having projections, which. are raised on its surface, to press-into the clay orother material,

makingthe tile lighter, and forming Ventilating channels; also to the beads b b, on the part which passes over the mold F, said beads forming grooves on the upper edges of the tile, which receive corresponding tongues on the tile which is next in the same course.

having the horizontal groove l near its upper end,

which forms a rib on the tile. The projections jij`A cutoff the clay at the ends of the ribs, which are formed in the clay by the recess between the projections on the roller. The curved depressions g g perform the same act. is a raised sloping portion, that forms a bevelon thc lower end of the tile, which tends to draw-the water from the edges of the tiles,-

near their lower ends. The pins t c', in molding, project through the clay, and make the holes for securing l the tiles tothe roof.

The fourth part of my invention relates to the mold E. The central portion ot said mold is a plain surface. Near the upper end is the horizontal groove d, to produce the same eiect as in the mold F. On each side of said mold are raised grooves, which form the tongue on the tile which fits into the grooves formed inthe tiles F. rlhe projections font off the clay, which forms the ribs. The pins c' form the holes.

Description of the Accompanying Drawing.

.Figure I is a View of the press, showing the frame A, slide-frame B, molds E and F, and press-roller D.

Figure ll, view of tile-mold E.

Figure III, view ot' tile-mold F.

Figure IV, longitudinal section of roller D, showing the projections a a, beads b b, and its relative po.- sition tothe molds E and F.

Figure V, end view of press-roller D, showing the projection cI and rib c.

A is a' frame, with the .frame B attached to its up per surface by slides.

The mold E is secured by gains cut in the outside edge of the slide-frame B, and theother edge of the mold is secured in like nianner to the center' rail.

. The mold F is secureddn the same way.

On the side of the frame B is secured a ratchet?, extending lengthwise. Said ratchet gears into a ratchetwheel, which is secured tothe end of the press-roller D, causing the frame B to pass back or forth. The slide can be Worked by a crank or any other convenient at tachment.

On the large part ot' the roller D, which is placed over the mold E, al'e the projections a d, which press into the clay and form recesses, which saves material and makes the tile light-er.

Between thc projections, and at each end, are grooves, which form ribs on the under side of the tile, making a bearing for the tiles on the roof. The depressions form air-channels for Ventilating the roofboards. v

The projecting rib c torms a groove near the lower end of the tile, which takes a corresponding horizontal rib formed near the upper end of the tile; and on its upper surface making a water-break, and helping to secure the tile in its place on the roof.

The smaller diameter of the press-roller D has, near itsends, the beads b b, which form grooves in the upper edge ofthe tile. This end of the roller has the same projections as the. larger one; also thc same rib c.

'lhc mold E has the raised longitudinal grooves c e, formed in its interior, saidgrooves forming tongues on-the tile, which lit into the grooves formed in the other tile by the beads l) l1 on the smaller diameter ot' the press-roller D.

d is ajhorizontal groove in the mold, which forms on the tile a rib, which projects above its surface near its upper end and lits into the groove which is formed on the under surface of the tiles. y

lhe pins'fi c' project through the clay in molding, and form holes for securing the tiles to the roof.

'lhc projections ff cut oit' the clay square at the ends of the ribs, the upper edge ofthe molds gauging the thickness ot' the tile.

G arc sloping projections in both molds, which form a bevel on the lower end of the tile to draw the water from the edge.

The mold F has its interior surface plain, and has the same .projection G as in E; also the same grooved projections f, and the pins 'it' for the same purpose.

The operation of this press is this:

Theframe B is brought forward. Sutiicient clay is placed in the molds, then passed back, when the press-roller -D imprints the grooves and depressions on the under side of the tile, and -at the same time ,are naar.

forcing the clay into y the other depressions of the molds.

The novelty in my improvement consist-s in the roller D, forming the depressions and groove in the under side ofthe tile, and forming.;` the upger surfe-ee of the JLiles in the molds E and F for forming the tongues e e in mold E, and the groove @for forming the ribs on the tile; also the pins 'i fi for forming the nail-holes.

YVhat I claim as my invention, and desire to seeure by Letters Patent, is

1. The roller D, with the projections a a a a, bends b b, and the ribs c c, substantially as and foivthe purpose as hereinbefore described.

2. The mold E, with the raised grooves e e, groove d, pins i z', :indslope Gr, substantially as and forY the purpose as hereinbefore setforth.

3. The rnoid F, with its groove (1,'pns t i', and slope G, substantially :1s and for the purpose ushereinbeiore set forth. v

4. The combination of the frame A, slidinbr frame B, roller D, and molds E and F, :di constructed, :Lrran ged, and operated as shown and described, for the purposes herein set fort-h.
